As far as I understand, women release egg cells on a relatively consistent schedule, and there are times when no egg cells are present in the uterus/fallopian tubes.

Why don't women release eggs more frequently than the 28 day-ish period? Why not once every day, for example? I understand that the uterus itself is not always susceptible to embryos, but it doesn't seem like a real detriment if the embryo is simply lost if the uterus is not ready at the right time.

Is it because human beings are unable to produce eggs as numerously as other animals, perhaps?

Edit: I don't see why this question is "opinion-based", if no clear explanation exists for the relative infrequency of oogenesis, please say so.

  • $\begingroup$ estrus periods are extremely common among animals. few vertebrates are fertile all the time. human are not unusual for how often the release ova, they are odd that we hide it. $\endgroup$ – John Jun 10 at 4:48

    $\begingroup$ To me, this is opinion based, because evolutionary “why” questions don’t have an answer beyond something like “because it allowed that organism to successfully reproduce.” $\endgroup$ – kmm Jun 10 at 17:09

    $\begingroup$ @user289661: Vertebrates in general don't have lower egg production rates. Some fish produce millions of eggs at a time. Amphibians can produce thousands, reptiles dozens or hundreds. Mammals & birds produce relatively few eggs because they invest heavily in parental care. $\endgroup$ – jamesqf Jun 10 at 17:14
